Bohler FOX CN 17/4 PH description: Basic electrode with strength properties for joint and fabrication welding of analogous precipitation hardening Cr-Ni-Cu alloyed rolled-, forged- and cast steels. Popular for components in the paper industry, rotors of compressors, fan blades, press plates in the plastic processing industry and for the aerospace industry. The electrode shows very good features in regard to arc stability, weld puddle control, slag detachability and seam cleanliness. Lowest hydrogen content in the deposit is a prerequisite (HD < 5 ml/100 g). The electrode is suitable for welding in all positions except vertical down.
